BOAT-CHOCK.

Specification of Letters Patent. Patented Dec, 10, 1918,

Application led August 1,3, 1918. Serial No. 249,699,

To all 'wlw/m, t may concern:

Be it known that I, PETER Gr. JOHNSON, a' citizen of the United States, and a resident of Astoria, Clatsop county, State of Oregon, have invented a certain new and useful Improvement in Boat- Chocks, of which the following is a specification.

The object of my invention is to provide a boat chock which is adapted to facilitate the insertion and removal of ropes or cables. f

I attain my object by a chock whichrhas an operable part which may be arranged in open and closed position, and when arranged the latter position, will hold the coils of the cable on the chock as illustrated in the accompanying drawings hereinafter more fully described. In short, my boat chock consists of a casting comprising upwardly projecting, inwardly curved arms, located at the opposite ends of the chock and spaced apart. Between the opposed extremities of these arms is a member rotatable on a vertical axis, having laterally projecting arms adapted for being alined with said rst mentioned arms; and I provide means for locking said rotatable member in place as positioned.

It is Jfurther my object to provide a boat chock of simple and durable construction as well as possessing said novel features.

In the drawings:

Figure 1 is a perspective of my chock, showing the same as closed, and also in dotted Outline indicating the movable piece as positioned when my chock is open;

Fig. 2 shows a longitudinal, vertical, central section of my improved boat chock; and

Fig. 3 is a partial view of the bottom of my chock.

The body, a, is a casting made with arms b, b at its ends, said arms projecting upwardly and curving inwardly so that their extremities, c, c, oppose each other but are spaced apart, as more clearly shown in Fig. 2. The base of the body is made with a supporting block d projecting a substantial distance above the plane of the base of said arms b, b. Said supporting block is cored out and therein rotates a vertical bearingpost e provided at its lower end with a ratchet-head 7". On the upper end of the vertical bearing-post, e, is removably secured a member 4g provided with laterally projecting arms h, L adapted to aline with the extremities '0, c of said arms b, b. I deem it preferable to make the top of said supporting block with a beveled edge, and provide the base of said member g with a beveled recess, so as to more securely seat the member g on the supporting block al.

The base of the body, @,is hollowe-d out so as to laccommodate the Operable parts. Bearings i, i', integralparts of 'the body a, are located, spaced apart, as shown in Fig. 2, and thereinreciprocates a pawl j.` The pawl, in the space between the bearings a, is provided with pins lc, and between said bearings there is mounted, on the pawl, a coil-spring Z, which, by bearing at one end on the pins k and at the other end upon the outermost bearing z", operates, normally, to throw the pawl y' into engagement with said ratchet-head f. m is a bell-crank handle connected by links n with the pawl y'.

By pulling up the handle fm, the pawl y' is withdrawn from the ratchet-head f, and

the member g may then be rotated into its Y open or closed position as desired. By then letting go of the handle m said rotatable part g is locked in place.

The body is provided with holes 0 in which to insert bolts for securing the chock in place.

I claim:

1. A boat chock comprising a body provided with upwardly projecting and inwardly and oppositely curved arms. the eX- tremities of said arms being spaced apart, a member located between said arms and rotatable on a vertical axis, said member having laterally projecting arms adapted to aline with the extremities of said arms of the body, and means for locking said rotatable member as positioned.

2. A boat chock comprising a body provided with upwardly projecting and inwardly and oppositely curved arms, the eX- tremities of said arms being spaced apart, the central part of said body being formed with a supporting block projecting a substantial distance above the plane of the base of said arms. a bearing post rotatable in said supporting block of the body provided with a ratchet head at its lower end, a member affixed on said bearing post and having laterally projecting arms adapted to aline with the extremities of said arms of the body` and means for locking said rotatable bearing post in place as positioned.

3. A boat chock comprising a body provided with upwardly projecting and inwardly and oppositely curved arms, the extremities of said arms being spaced apart, the central part of said body being'formed with a supporting block projecting a substantial distance above the plane of the base of said arms, a bearing post rotatable in said supporting block of the body provided With a ratchet head at its lower end, the top of said supporting block being beveled and the base of said member carried by said bearing post having a conforming beveled recess, and nieansfor locking saidr rotatable bearing post in place as positioned.

4. A boat chock comprisinga body pro vided With upwardly projecting and inwardly and oppositely curved arms, the eX- tremities of Said arms being spaced apart,

the central part of Said body being formed with a supporting block projecting a substantial distance above the plane of the base of said arms, a bearing post rotatable in said supporting block of the body provided with a. ratchet head at its lower end, the top of said supporting block being beveled and the basel of saidv member carried by said bearing post having a conforming beveled recess, a pawl longitudinally movable in the base of saidbody engaging with said ratchet head, a spring normally holding said paWl in engagement With said ratchet head, a bell crank handle, andl a link connecting,` the latter With said pawl.
